Attend this Premier Training and Gain Insight into
This training will assist both those whose day to day work involves them in the application of protection design, coordination and relay setting, and also to those in less directly associated areas of generator and power station protection system design. This training has been prepared specifically to meet the requirements of:
• Protection Design Engineers, to identify protection implications and to ensure design, coordination and relay setting principles provide the necessary levels of speed, security, dependability and safety
• Planning Engineers, to identify the difficulties in providing protection for various power system configurations under review
• Maintenance Engineers, to ensure that system protection is not compromised as primary and/or secondary system plant is removed from service during maintenance
• Circuitry Design Engineers, to ensure that protective schemes are implemented in a manner to provide optimum performance
• Commissioning and Project Management Engineers, to ensure the actual field installation of the protection scheme and associated relay settings meets the design requirements
• Technicians, to understand the importance of their role in installing, testing and maintaining effective, reliable, dependable and secure protection systems
This 2-day training focuses on the principles of generator and power station protection schemes, including their application to generator faults, generator events, external power system events, and power station motor, busbar and transformer faults.
Delegates will learn
• Principles of power station protection schemes & the art of scheme selection
• The generic processes associated with determination of optimal settings
• Configurations for the protection relays and schemes associated with power station generators, motors, busbars and transformers.
• Technicians, to understand the importance of their role in installing, testing and maintaining e ective, reliable, dependable and secure protection systems.
Trainings at Global Industries Intelligence
Global Industries Intelligence training courses are thoroughly researched and structured to provide intense practical training applicable to your organization.
• Combinations of educational presentations, productive in-session assignments and participant collaboration to provide actionable learning
• Strictly limited numbers to allow for greater interaction and one-on-one interaction with the trainer
• Detailed pre-course questionnaires to allow you to tailor the program to address your individual concerns
• Hard and soft copies of presentation materials and tools
Pre-course Questionnaire
To ensure that you gain maximum benefit from the event, a detailed questionnaire will be sent to you to establish some of you background information and exactly which of the topics covered in the seminar are of major importance to you and major issues related to those topics. The course trainer will analyse the completed forms. As a result, we ensure the course is delivered at an appropriate level and that relevant issues will be addressed. The comprehensive course material will enable you to digest the subject matter in your own time.
